The MC Unit is not designed to perform linear interpolation or circular arc inter-
polation with horizontal articulated robots or cylindrical robots. The MC Unit can,
however, perform PTP control with these robots.

Heed the following precautions when wiring the MC Unit to the servodrivers and
motors.
Electronically controlled equipment may malfunction because of noise gener-
ated by power supply lines or external loads. Such malfunctions are difficult to
reproduce; hence, determining the cause often requires a great deal of time.
The following tips should aid in avoiding noise malfunction and improving sys-
tem reliability.
Use electrical wires or cables of designated sizes as specified in the instruction
manual for the servodriver. Use larger size cables for the FG lines of the PC or
the driver and ground them over the shortest possible distance.
Separate power cables (AC power supply lines and motor power supply lines)
from control cables (pulse output lines and external input signal lines). Do not
group the two types of cable together or place them in the same conduit. Use
shielded cables for control lines.
For inductive loads such as relays or solenoid valves, connect surge absorbers.
Note Connect a surge-absorbing diode or surge absorber close to the relay. Use a
surge-absorbing diode with a voltage tolerance at least five times greater than
the circuit voltage.
